Starting up network services from xinetd
xinetd is started on bootup, and listens on ports designated in /etc/xinetd.conf for incoming network connections. When a new connection is made, xinetd starts up the corresponding network service.
You should disable any unnecessary services from being started from xinetd as part of securing your machine. The way to do this is to edit that service's configuration file. xinetd's main configuration file is /etc/xinetd.conf. At the end of the xinetd.conf file is a line that indicates that all the files in the /etc/xinetd.d are also included in the configuration. This means that you need to go through the files in that directory as well in order to turn off any services you don't want.
